Would be awesome if there's a way for us to tag people/images while scheduling each posts.
We have now shipped the ability to add People Tags (and Geo Tagging) to IG posts!
One restriction is they have to be scheduled as "auto-publish", as this will only work going through the new Instagram API. Also - we can't query the IG API for people's names, so we unfortunately cannot do autocomplete on names
Hope this feature helps!
